at first i thought this would not be so difficult to make something like this photo...I was wrong...I worked many hours to get this result and i'm not absolutely satified.I sould have spend more more time on cloth simulation to get something better. I'm noob in cloth simulation, i've learned a lot, i will have better results next time

Great job!From my work with Vickie in the past, I know she makes a lousy dancer right out of the box (her joints just aren't made for it), so you did a great job in setting her up! Only two things that I'd remark from a dancer's point of view, is that her left shoulder could be pushed down a bit lower and her knees could be stretched júst a bit more. Or rather, from a 'normal' person's point of view, overstretched. Fantastic render though, you achieved a high amount of realism in this!
